The negative impacts of racism, including experiences of racial trauma, are well documented (e.g., Bryant-Davis & Ocampo, 2006; Carter, 2007). Because of the deleterious effects of racial trauma on Black people, interventions that facilitate the resistance and prevention of anti-Black racism are needed. Critical consciousness is one such intervention, as it is often seen as a prerequisite of resistance and liberation (Prilleltensky, 2003, 2008). To understand how individuals advance from being aware of anti-Black racism to engaging in actions to prevent and resist racial trauma, nonconfidential interviews with 12 Black Lives Matter activists were conducted. Using constructivist grounded theory (Charmaz, 2014) under critical-ideological and Black feminist-womanist lenses, a model of Critical Consciousness of Anti-Black Racism (CCABR) was co-constructed. The 3 processes involved in developing CCABR include: witnessing anti-Black racism, processing anti-Black racism, and acting critically against anti-Black racism. This model, including each of the categories and subcategories, are detailed herein and supported with quotations. The findings and discussion provide context-rich and practical approaches to help Black people, and counseling psychologists who serve them, prevent and resist racial trauma.
